So my boyfriend and I are preparing to have sex. He actually has a problem where he never ejaculates but only precums. I am planning on getting the depo-provera shot and then we were going to have sex the same day. If we use a condom that has spermicide will we be protected? (I know the shot doesn't work immediately)

If you use a condom correctly and for all genital contact, it is 98% effective at preventing pregnancy. You can read more on how to correctly use a condom here: Condom Basics: A User's Manual

There is no need to use spermicidal condoms. There is not enough spermicide on them to really add much protection, and some people find that the ingredients in spermicide irritate them.
